What is the hardest part in writing test cases?

To me, memorizing relationship between modules to make sure my test cases cover most commonly used combinations is the hardest. And I'm still figuring out better solution.

Writing questions about it on Hacker News has been goddamn hardy!

Mocking third party libraries is pretty hard.

Can you explain more in a scenario example?

The hardest part is planning what you are going to write; that is, identifying the most important of the possible things to test. The writing itself should be fairly straightforward.

How are you identifying important cases to cover right now? I rely on QA and she uses TestRail to manage but it's still common to miss out some important flow.
